The American Canyon Placers is a gold mine located in Pershing county, Nevada.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Land ownership: BLM Administrative Area
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comment (Production): ESTIMATED $10,000,000. (?) LARGELY FROM AMERICAN & SPRING VALLEY CANYONS. ALSO PRODUCTION OF PROBABLY LESS THAN 100 FLASKS OF MERCURY.
Comment (Development): MOST OF THE PLACER MINING WAS DONE IN THE 1880'S AND 1890'S BY CHINESE MINERS WHO DUG SHAFTS 40-100 FT INTO THE GRAVELS.. NO DOUBT VERY EARLY IN THE MINING, THE CINNABAR OCCURRING WITH THE GOLD IN THE STREAKS OF HEAVY MINERAL CONCENTR-ATIONS WAS NOTED. ACCORDING TO RANSOME, THE OCCURRENCE OF "BOW-LDERS" OF CINNABAR IN THE PLACER GRAVELS LED TO A SEARCH FOR T-HEIR SOURCE AND RESULTED IN THE EARLY DISCOVERY OF THE DIXIE (-KAOLIN) AND NEVADA ALMADEN LODE DEPOSITS FARTHER UP AMERICAN C-ANYON. IN 1941, AFTER A LONG PERIOD OF LITTLE INTEREST IN THE -GOLD PLACERS, THE CHINATOWN QUICKSILVER PLACER DEPOSIT WAS STA-KED IN AMERICAN CANYON NEAR THE CENTER OF SEC 18 BY J. L. ALGE-R, MERRIL FISK AND W. F. FISK. IN 1942, RECORDS INDICATE INDEP-ENDENT PRODUCTION BY TWO OF THE PARTNERS YIELDING 32 FLASKS HG-. NO OTHER MERCURY PRODUCTION FROM THE PLACER DEPOSITS IS RECO-RDED, BUT IT SEEMS VIRTUALLY CERTAIN ADDITIONAL MERCURY WAS RE-COVERED HERE BOTH IN THE EARLY PERIOD OF EXTENSIVE MINING BY T-HE
Comment (Development): FRUGAL CHINESE AND IN OPERATIONS IN THE EARLY 1940'S. IN 19-80 THERE WAS RENEWED INTEREST IN THE GOLD PLACER DEPOSITS WHIC-H MAY LEAD TO RECOVERY OF A LITTLE MERCURY AS A BYPRODUCT.
Comment (Deposit): GOLD WAS CONCENTRATED IN A PAY STREAK UNDERLAIN BY CLAY AT AN AVERAGE DEPTH OF 60 FEET BUT AT SHALLOWER DEPTH AT THE UPPER END OF THE PLACER THAN AT THE EDGE OF THE RANGE. PARTICLES OF CINNABAR RECOVERED FROM THE GRAVELS LED TO THE DISCOVERY OF SEVERAL MERCURY DEPOSITS IN THE AMERICAN CANYON DRAINAGE.
Comment (Workings): CHINESE MINERS DUG SHAFTS 40-100 FT INTO THE GRAVELS. NUMEROUS DREDGE AND PLACER TAILINGS COVER OVER 100 ACRES.

Nevada has a total of 368 distinct gold districts. Of the of those, just 36 are major producers with production and/or reserves of over 1,000,000 ounces, 49 have production and/or reserves of over 100,000 ounces, with the rest having less than 100,000 ounces. Read more at Gold Districts of Nevada.
